Conrad Janis – 93
Conrad Janis has undoubtedly made a lot of effort to keep alive the traditional jazz form of music, as he himself played the trombone. Apart from that, he worked extensively as an actor as well. His most notable performance was in the 1996 film The Cable Guy.
His most recent work was in the 2012 film Bad Blood, which is also supposedly his last film as he has seemingly retired from showbiz. This seems to be the right choice, not because he has gone mostly bald, but because he has been working for a very long time and deserves some time off.
